Need extra key/fob new to me LS430
Hello all.....long story but wrecked my pristine '04 Black/Black LS430 in March. Didn't think I would find another so picked up a clean LS460. Not long after a clean Black/Grey '05 LS430 popped up so I grabbed it. Working out a few things. One is that there is only one key/fob. I have a key guy but he is unable to program a new one. I hate to go to the dealer but want another. Any tips for me? Thank you for your help.

Unfortunately, that or a dealer are the only 2 options I'm aware of...

I too would like to have an "extra" key. It is easy to find Lexus blanks and NOT so easy to find someone to cut the key, but I have read these articles about going thru a series of: inserting good key, then new key to program, opening doors, pumping the gas pedal and tapping the brake while rubbing your head and patting your stomach. Is any of this true? Has anyone tried this? Posted November 7, 2007Hi all
Apparently this is the way to programme a new key although it won't do the smart key bit...
Tried this on a USA spec key bought off eBay but they are obviously different to ours...
Thought I'd add this below as it may help someone...
LEXUS KEY PROGRAMMING
First two methods are for programming the transponder chip in new keys
and the immobilizer allowing the new keys to start the car.
Process works with all keys - remotes, valet, non-remotes
Method 1:
Requires one working LEXUS Master Key.
1. Enter the car with the existing master key and close all doors.
Simultaneously depress and release both the brake and the accelerator
pedals.
2. Within 5 seconds, insert the existing master key into the ignition.
DO NOT TURN THE KEY.
3. Within 15 seconds of inserting the ignition key, depress and release
the accelerator pedal 5 times.
4. Within 20 seconds, depress and release the brake pedal 6 times and
then remove the existing master key key from the ignition.
5 Within 10 seconds, insert the new key into the ignition.
6. Depress and release the accelerator pedal one time. The security
light should now begin flashing to indicate that the computer is reading
the new key and programming the system.
7. Leave the new key in the ignition for 80 seconds. When the security
light stops flashing the new key is registered, Remove new key and
depress and release brake pedal 1 time. The programming process should
be complete.
8. Test the new key. Place the key into the ignition and verify that the
car will start.
9. If this is a new remote master key, test the remote functions on the
new key.
Method 2:
Requires one working LEXUS Master Key.
1. Make sure all doors and windows are closed.
2. Insert Master key into the ignition cylinder.
3. Cycle the ignition cylinder from On to OFF five times.
4. Open and close the driver side door 6 times.
5. Remove the Master Key and insert the new duplicates key.
6. TURN THE IGNITION CYLINDER ON.
7. The new key will be registered after 60 seconds. The THEFT light on
the dashboard will go out, indicating that programming has been completed.
LEXUS REMOTE PROGRAMMING
Method 1:
1. Sit in the driver's seat and lock all the doors.
2. Unlock and open the driver's door.
3. Insert the key into the ignition and remove it (don't turn it...just
remove it).
4. Using the MANUAL lock switch on the driver's door, lock and unlock
the door 5 times.
5. Close the door.
6. Open the door.
7. Lock and unlock the driver's door 5 times (I'm almost certain you use
the MANUAL lock switch again, but if this sequence fails to work, try
again with the power switch). Insert the key into the ignition and turn
it to the "ON" position. Remove the key.
8. The driver's door will now lock and unlock itself one time.
9. Press and hold the "LOCK" button on the key fob for at least 1 second.
10. Close the driver's door.
11. Open the driver's door.
12. Press and hold the "LOCK" button on the key fob for at least one
second.
13. Close the driver's door.
14. Press and hold the "LOCK" button on the key fob. The door will lock.
15. Press and hold the "LOCK" button on the key fob again. The door will
unlock.
Method 2:
1. Driver door open and unlocked. Key out of the ignition
2. Insert the key and remove 2 times in 5 sec.
3. Close and open driver door 2 times in 40 sec.
4. Insert the key and remove it again from ignition.
5. Close and open driver door 2 times in 40 sec.
6. Insert the key in ignition,
7. Close the door,
8. Turn to on and back to lock in 1 second intervals. 1 time for add, 2
times for rewrite, 3 for confirmation 5 for prohibition. (yes, there is
no “4”)
9. Remove the key
10. Power lock will cycle to confirm
11. For add or rewrite mode within 40 sec of the confirmation,
A. press “lock” and “unlock” buttons of the FOB at the same time between
1 and 1.5 seconds.
B. within 3 sec press “Lock” button for more than 1 sec and release.
C. If it’s correct, the power door lock will cycle once. If it’s wrong
the door lock will cycle twice.
You should be all set.
